Description

Mobile communication equipment and method for coordinating operations of receiving cell broadcast messages using different subscriber numbers and scheduling information shared between operations

This application generally relates to cell broadcast message processing, and more specifically, to equipment and methods for coordinating operations of receiving cell broadcast messages using different subscriber numbers and sharing scheduling information between operations.

With the increasing demand for ubiquitous computing and networks, various radio access technologies (RAT) have been developed, such as Global System for Mobile communication (GSM) technology, general packet radio Service (General Packet Radio Service, GPRS) technology, Enhanced Data rates for Global Evolution (EDGE) technology, Universal Mobile Telecommunications System (UMTS) technology, Interim Standard 95 (Interim Standard 95, IS-95) technology, Code Division Multiple Access 2000 (CDMA 2000) technology, CDMA 2000 1x Evolution-Data Optimized or Evolution-Data (CDMA 2000 1x Evolution-Data Optimized or Evolution-Data, CDMA2000 1x EV- DO) technology, Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) technology, Worldwide Interoperability for Microwave Access (WiMAX) technology, Long Term Evolution (Long Term) Evolution, LTE) technology, Time-Division LTE (TD-LTE) technology, enhanced LTE (LTE-Advanced, LTE-A) technology, etc.

Traditionally, a cellular phone only supports one RAT with one subscriber number, and is used to always provide users with mobile communication flexibility through the supported RAT using a single subscriber number. However, in an upward trend, more and more people find that having additional subscriber numbers is a good way to reduce their mobile service charges (including voice and/or data services) or to separate personal and business phone calls. In order to reduce the burden of carrying two cellular phones for two separate subscriber numbers, so-called dual-card cellular phones have been developed, which generally support at least two RATs that use separate subscriber identification cards to provide individual mobile services for individual subscriber numbers . The dual card design allows two RATs to be active at the same time, and allows calls to be made or received on any subscriber number at any time.

Generally, in order to reduce costs, most dual-card cellular phones are equipped with a single radio frequency (RF) device. Since a single RF device is shared by the transmission/reception operations associated with two separate subscriber numbers, only one subscriber number is allowed to occupy a single RF device for transmission/reception operations at any given time. In the case of Cell Broadcast Service (CBS) messages or scheduling messages configured to be sent to dual-card cellular phones in two or more time slots, the reception associated with two separate subscriber numbers Operations may conflict and usually use a round-robin scheduling strategy to assign a single RF device to any subscriber number. CBS messages are usually used in public alert systems, such as Commercial Mobile Alert Service (CMAS) or Earthquake and Tsunami Warning System (ETWS) to issue warning messages on behalf of public agencies, and CBS messages can Decompose into multiple segments/blocks for transmission in multiple time slots.

Figure 1 is a schematic diagram showing a receiving operation associated with two separate subscriber numbers using a loop scheduling strategy. As shown in Figure 1, the communication with the same cell using two separate subscriber numbers (assuming that the two subscriber numbers belong to the same subscriber) is configured to be in Discontinuous Reception (DRX) level 1 scheduling mode, and Each subscriber number is configured to receive the corresponding CBS or scheduling information block timing (occasion) is shown in gray background, where the conflict of the receiving operation occurs at the timing 0, 6, and 12. According to the loop scheduling strategy, subscriber number #1 will not be able to receive blocks sent in timing 6, and subscriber number #2 will not be able to receive blocks sent in timings 0 and 12. Therefore, two separate SIMs cannot receive complete CBS messages or scheduled messages.

In order to solve the above problems, this application proposes to give priority to one subscriber number at a time to receive all blocks of CBS messages or scheduling messages, allowing at least one subscriber number to receive complete CBS messages or complete scheduling information. In addition, this application proposes to share scheduling information between operations associated with a plurality of subscriber numbers, so as to receive their respective CBS messages when these subscriber numbers all reside on the same cell.

The station receives one or more first CBS messages, and shares the scheduling message with the second receiving operation to use the second subscriber number to receive one or more second CBS messages from the cellular station through a single RF device.

In the fourth aspect of the present application, there is provided a method for sharing scheduling information between operations of receiving CBS messages using different subscriber numbers in a mobile communication device including a single RF device.

In this embodiment, the method of coordinating the operation of receiving cell broadcast messages using different subscriber numbers can be applied to multi-card and single RF cellular phones (for example, mobile communication device 210), where multiple cards are camped on the same cell.

Specifically, the method of coordinating the operation of receiving cell broadcast messages using different subscriber numbers can be implemented in a code loaded and executed by a baseband processor (for example, the processor 21 or 21').

First, the mobile communication device uses the first subscriber number to receive one of the first CBS message or the first scheduling message from the cell station through a single RF device (step S510). In other words, the first CBS message or the first scheduling message is configured to be sent in a plurality of blocks from the cellular station to the mobile communication device, and now the mobile communication device has received one of the blocks.

In one embodiment, the mobile communication device may determine whether the received block is the first block of the first CBS message or the first block of the first scheduling message, and if so, the method proceeds to step S520.

Next, instead of using the second subscriber number to receive any block of the second CBS message or the second scheduling message from the cell station through a single RF device, the mobile communication device preferentially uses the first subscriber number to receive multiple blocks from the cell station. The remaining blocks (step S520). That is, the receiving operation associated with the first subscriber number has priority over the receiving operation associated with the second subscriber number. Specifically, if the cell station belongs to the UMTS network, the receiving operation includes Common Traffic Channel (CTCH) decoding, or when the cell station belongs to the GSM network, the receiving operation includes Cell Broadcast Channel (CBCH). decoding.

Afterwards, in response to receiving all the plural blocks, the mobile communication device reassembles the plural blocks to obtain the first CBS message or the first scheduling message (step S530), and the method ends.

In one embodiment, the mobile communication device may reset the priority order of receiving operations associated with the first subscriber number to an initial value (for example, level X) after step S530.

In step S601, the RLC layer of the UMTS protocol stack for the first subscriber number receives the CTCH block (for example, the first CTCH block) of the CBS message or the scheduling message from the lower layer.

In step S602, the RLC layer of the UMTS protocol stack for the first subscriber number increases the priority of CTCH decoding in the lower layer by 1 (ie, set to X+1).

In step S603, the RLC layer of the UMTS protocol stack for the first subscriber number receives the remaining CTCH blocks of the CBS message or the scheduling message from the lower layer.

In step S604, the RLC layer of the UMTS protocol stack for the first subscriber number reassembles all the received CTCH blocks to obtain a complete CBS message or a scheduled message, and sends the complete CBS message or a scheduled message to the broadcaster And multicast control (Broadcast and Multicast Control, BMC) layer.

In step S605, the RLC layer of the UMTS protocol stack for the first subscriber number resets (ie, reduces) the priority order of CTCH decoding in the lower layer to the initial value X.

In step S701, the RR layer of the GSM protocol stack for the first subscriber number receives the CBCH block (for example, the first CBCH block) of the CBS message or the scheduling message from the lower layer.

In step S702, the RR layer of the GSM protocol stack for the first subscriber number increases the priority of CBCH decoding in the lower layer by 1 (ie, set to X+1).

In step S703, the RR layer of the GSM protocol stack for the first subscriber number receives the remaining CBCH blocks of the CBS message or the scheduling message from the lower layer.

In step S704, the RR layer of the GSM protocol stack used for the first subscriber number reassembles all the received CBCH blocks to obtain the complete CBS message or the scheduled message, and sends the complete CBS message or the scheduled message to the short message Service cell broadcast (Short Message Service Cell Broadcast, SMSCB) layer.

In step S705, the RR layer of the GSM protocol stack for the first subscriber number resets (ie, reduces) the priority order of CBCH decoding in the lower layer to the initial value X.

It should be understood that the protocol layer described in the embodiment in FIG. 7 is only for illustrative purposes and is not intended to limit the scope of the application. For example, each GSM protocol stack may include more layers, such as a mobility management (Mobility management, MM) layer and a connection management (Connection management, CM) layer.
